Single action audio prompt interface utilising binary state time domain multiple selection protocol

ABSTRACT

An interface protocol for the functional manipulation of complex devices such as consumer electronic devices without the necessity of the visual feedback via textual or graphic data, wherein the sensor functions change with time rather than placement, so that a user action biases a binary state switch, which is correlated to a timed audible audio data stream, the correlation indicating the desired action selected by the user.

FIELD OF THE INVENTION

This invention relates to a user interface. The user interface guides the user through option menus and the selection process.

BACKGROUND

The present invention addresses problems presented by conventional user interfaces, for example in consumer electronic products. It relates to a process and the configuration of apparatus that can accurately and automatically interpret the user's desired selection without the requirement that the user be able to read. One aspect of the interface of the present invention resides in its ease of use, especially for children, for illiterate people and people less technically able. The device can be embedded inside almost any product, for example, without intending to be limiting, telecommunication devices such as cell phones embedded in a product, without affecting the external aesthetics of the product.

Applicant is aware of prior art within the field of user interfaces for consumer electronic products, for example interfaces employing voice recognition, graphic touch panels, and intelligent keypads. Such prior art user interfaces for consumer electronic products consist of a broad range of technology mixes. The current trend is to use a more organic style of interface such as voice recognition or graphical interfaces rather than arrays of mechanical buttons. Some devices attempt to guess a user's most probable decisions, making navigating complex decision trees more tolerable. The present invention is derived out of necessity for an easy-to-use interface that, for example, may be embedded in electronic equipment so for example to operate without a keypad or display.

One object of this invention is to provide an alternative method of operating equipment for example such as cellular or wireless telephones or other devices such as equipment which may be operated using binary input devices including but not limited to push buttons, switches, digital signals, microphones, motion sensors, light detectors, rotary encoders, voice recognition processors, or processes, wherein audio prompts guide the user through options, and the user responds with a timely action to accept or reject the specific option presented during a corresponding time window.

SUMMARY

In the present invention, the user of a device is presented with an action, an option or a series of options via audio messages. The user indicates acceptance or rejection of an option with a timely action, for example such as pressing a button disguised within a product such as a plush doll. The timely action must occur during the time window in which the audio message implicitly or explicitly indicates the intention to accept or reject an option. Otherwise, the interface indicates the default selection to the device. For example, a default selection may be to cycle a number of times through a menu, for example three times, and failing getting a response backup one level in a decision tree and again cycle through the menu at that level a number of times, and failing getting a response backup yet a further level, and so on until the interface or device is left in a standby mode. The interface is thus well adapted for use by a child, or for example by a visually impaired person, or even merely for use by people who are driving automobiles and should not be taking their eyes from the road ahead, because the interface does not require an action by the user as no action is treated as a selection choice thus differentiating from prior art for example which presents a three position tree to a handicapped person thus requiring an action from the person.

The invention is thus, in one aspect, a process of navigating menus or selecting actions or options. The process may utilize a sensor system configured to behave as a binary state switch along with an audio presentation and feedback system. These two elements are synchronized to permit correlation analysis of signals, which yields information or signals that indicate the user's selected option or desired action.

The novelty lies, at least in part, in the ability of a device, such as a binary push button, to select one of multiple options by indicating the option as desired or undesired as they are presented through time via speech. Acceptance or rejection is indicated by the presence of one or the other of the two possible binary states during the corresponding time window.

The selection time window can be within the time domain of spoken words or sounds of the prompt, which may include quiet time and may also include, or consist only of, other audible queues or music.

This interface protocol permits functional manipulation of complex devices, such as personal telecommunication devices, consumer and commercial electronic devices and appliances, motion sensor, light detector, rotary encoder, voice recognition processor, without the necessity of the visual feedback via textual or graphic data. Since the sensor functions change with time rather than placement, both visual and tactile demands placed upon the user are dramatically reduced, offering an advantage over the complex array of graphic symbols and the symbolic placement of buttons found on multifunction keypads. In the present invention an action is converted to an electrical impulse, which is correlated to a precisely timed audible audio data stream. The correlated data indicates the desired action or option selected by the user. This allows a device such as those listed above to be embedded in a product without altering the external aesthetics of the product. In some cases, the ability to be hidden within the product will be an essential component of the invention's application.

In a further aspect, the present invention is a communication protocol that defines the parameters of actions, data transfer, acknowledgment and response for the purpose of a user interface, for example in a consumer electronic device. The user/operator listens to a stream of audio messages that indicate available options. The user selects an action, an option or an optional path through a menu tree by either doing, nothing, or by biasing, for example such as toggling or otherwise reversing the state of a binary state device, so as to select the alternative choice, action or path available at that moment. When the user makes no selection, it indicates acceptance of a default choice, direction or action such as backing up a level in a decision or menu tree.

In one embodiment, the audio stream may present an ongoing list during which the user intervenes to select the desired option. The default action in this embodiment may then be to merely present the next item in the list.

The present invention may be described as a time domain multiple selection protocol in which for example, and without intending to be limiting, a binary state indicates a selection by inversion of the binary state during the defined time window for the desired selection utilizing mechanical, electromechanical and electronic circuitry. The present invention requires the presence of three key elements, an input mechanism, an audible output system and a method for keeping track of the state of the input device as the messages are being presented. The user interface is a timing based multiple selection protocol consisting of mechanical, electromechanical and electronic circuitry for a novel method of making and selection from a menu or list of items.

Thus, in summary, the present invention consists of a time domain, multiple selection protocol in which a selection of an option is made during the defined time window for the desired action or option. The action or option is presented in an audible audio information stream that is precisely timed or synchronized with the monitoring of sensors to allow electronic signals to indicate and be processed in such a manner as to yield information regarding the user's choice.

The audio stream presents a series of actions or options from which the user may select an option via any input device, such as a push button switch. The device may also operate with for example a limited binary state voice recognition interface, motion sensors, light sensors, etc. A preset default option is assumed unless indicated by the user causing an input during the time domain of presentation of information pertaining to the desired option. Presented information is any audio information that could be used to indicate the nature of an option and its selection time frame.

The configuration of electronic components, circuitry, mechanical or electromechanical sensors and/or computer software/firmware for providing information to the user and the host system regarding the user-desired action or option uses such physical resources and time stamping to determine the user's activity and report information via an electronic or mechanical signal that a processor can process as a specific action or intent.

A device incorporating the present invention may operate while embedded in another product, for example a consumer electronics product, without altering the external aesthetics of the product, and without visually disclosing the embedded functionality. Put another way, the present invention may be summarized as an audio prompted interface device using a time domain multiple selection protocol wherein the device includes:

-   -   (a) a device housing,     -   (b) a processor and cooperating memory and a power supply         mounted in the housing,     -   (c) an audio broadcaster mounted in the housing and cooperating         with the processor for audibly broadcasting outside of the         housing a sequenced series of audible prompts supplied by the         processor to the audio broadcaster,     -   (d) an input device or sensor mounted in the housing for         receiving input from a user, in one embodiment the input for         binary biasing of an input switch between opposite binary states         in response to a single prompt of the series of audible prompts,     -   (e) a timer cooperating with the processor, the processor         correlating the response to the single prompt with a         corresponding single time domain within a sequential series of         time domains timed by the timer, and     -   (f) the processor correlating the single time domain with the         single prompt and executing a single action corresponding to the         single prompt according to an instruction set in the memory,         wherein, if for example the single action is a telecommunication         action, the processor executing the single action in further         cooperation with a telecommunication transceiver mounted in the         housing.

The device housing may be a flexible surface and the input receiver mounted beneath the flexible surface. The device housing may have an audio transmitting surface and the broadcaster may be mounted beneath the audio transmitting surface.

In one aspect of the present invention, the product or device may be a plush toy, which may have at least one appendage. Such an appendage may be pivotally mounted to a body of the plush toy. The appendage may cooperate with a processor so that a first position of the appendage relative to the body switches the processor into a stand-by mode, and a second position of the appendage relative to the body switches the processor into an active mode so as to trigger the series of prompts. Advantageously the appendage is an opposed pair of elongate appendages such as arms, legs or the like. The pair of appendages may pivot relative to the body between a resiliently clamped, closed position wherein the appendages are adjacent, and a spread position wherein the pair of appendages are spaced apart. The first position may be the closed position and the second position may be the spread position.

In one embodiment, the first and second positions lie substantially in a first plane. In a third position the pair of appendages are elevated out of the first plane. In the second position the audio broadcaster audibly transmits at a first audible volume and in the third position the audio broadcaster audibly transmits at a second audible volume, wherein the first audible volume may be greater than the second audible volume. In the third position the ends of the arms, which may be shaped as hands, cup a mouth of the plush toy. In this embodiment the audio broadcaster may be mounted behind the mouth of the plush toy. When the ends of the arms are hands in the first position the hands are together in front of the plush toy, and in the second position the hands are widely spread apart.

In a further aspect of the present invention the input switch may be a push-button switch, and the series of audible prompts may be prompts in a multi-level menu tree. The input switch may also be a microphone in conjunction with software to detect any audible response versus no audible response, the audible response biasing, for example a binary switch to its opposite binary state. The series of audible prompts may comprise a sequentially audibly broadcast list of names from a list of names in the memory, wherein the single prompt is a single name from the list and the single action corresponding to the single name is to dial a telephone number, from a corresponding list of telephone numbers, corresponding to the single name. Advantageously the list of names may be statistically ordered based on frequency and time of calling by the user so as to present first numbers most likely to be called. In one preferred embodiment, the input button switch may be biased a plurality of times in rapid succession and the action corresponding to the single action is different depending on the number of times the input switch is biased in rapid succession. In another preferred embodiment the speed of audible presentation of the prompts may be increased by compressing the audio data in the prompts, and in such a case the prompts may be sped-up in an adaptive feedback loop so as to increase the presentation speed until user mistakes meet a threshold cut-off level.

The method of the present invention may comprise the steps of:

-   -   (a) audibly broadcasting outside of the housing from the         broadcaster a sequenced series of audible prompts supplied by         the processor to the audio broadcaster,     -   (b) receiving input to the input receiver from a user, the input         for example toggling a binary state input receiver in response         to a single prompt of the series of audible prompts,     -   (c) timing, by the timer, a sequential series of time domains,     -   (d) correlating, by the processor, the response to the single         prompt with a corresponding single time domain within the         sequential series of time domains,     -   (e) correlating, by the processor, the single time domain with         the single prompt, and     -   (f) executing a single action corresponding to the single prompt         according to an instruction set in the memory.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

What follows is an example of one embodiment according to the present invention which is not intended to be limiting. Thus, with reference to the timing diagram of FIG. 1, the upper line describes an audio signal, that is, a plot of signal intensity over time. As a message is spoken or otherwise audibly broadcast to a user by a telecommunication device employing the interface of the present invention, the audible signal level increases as diagrammatically illustrated in the “audible signal” line and time transpires. The middle and lower lines indicates two of the three possible selections, so that in the case where the user desires to “phone mom”, the user's timely input (for example by squeezing a flexible toy so as to toggle a push-button switch) would cause a waveform having a pulse within the “phone mom” selection time window. Thus, waveform “a” would result in a selection to phone mom. The pulse 10 indicating a state change could have occurred any time between time lines 12 and 14. The pulse 16 in waveform “b” is well outside the phone mom selection window and would make a different selection, in this case to “phone home”. This is a simple example of the user interface of the present invention.

Users of this interface are not required to look at the telecommunication device during operation, eliminating the need for displays and the interpretation of visual symbols on buttons or graphics on the displays, and also eliminating components such as the keypads popular in the wireless telephone industry today. Also, the user's finger, or other selector, can maintain close proximity while making a selection, which makes the device easier, and in some conditions safer, to use. The input from the user may be a physical toggling of a binary switch, or it may be non-contact biasing of a binary state switch by, for example, the use of motion or light detectors, or by audible sound sensors, voice recognition etc.

The interface of the present invention is a departure from current interface design in its operational style, its elegance and simplicity. However, it does have its drawbacks. It tends to be slow compared to normal operation of a conventional keypad and is best suited to tasks that do not require the user to remember past actions. For example, entering long strings of numbers can be taxing for the user.

A physical embodiment of the present invention may have three elements, namely:

-   -   (a) means, such as a processor (including associated memory), a         microphone and a power supply, of generating and broadcasting a         meaningful and audible audio stream which includes a sequential         menu tree series of prompts to direct the user's         decision-making;     -   (b) a sensor that senses and transmits or applies a signal to         the processor indicating a user input timed to denote the user's         desired option; and,     -   (c) a timing and correlating processor (which may be the same         processor as in (a) above) that correlates in time audio         presentation of the audio stream and user input signals.

Further processing features enhance operation of the interface of the present invention, namely:

-   -   (a) statistical ordering; that is, the processing of numbers         such that the numbers that are most pertinent to the user are         determined by statistical analysis based upon both call time and         frequency;     -   (b) audio compression; that is, the process of compressing         sounds so as to increase the speed of presentation of audible         prompts (for example a sequential counting of numbers) in the         time domain while maintaining essential message intelligence for         the purpose of presenting more information in a given instant.         This is desirable for use in a voice prompt based user interface         for example in a personal communications device and may be         accomplished by, for example, removing 40 percent of the         digitized audio data without causing a sound frequency shift;     -   (c) adaptive feedback; that is, monitoring activities that are         subliminal to the user but detectable to the system to control         the nature of the user interface with the intention of making         the user interface more effective for the user. The activities         of most interest in are those that affect the speed of         presenting or processing of information that is fast enough to         keep interest and slow enough to be usable in a reliable manner.         By using audio compression, as the user leaves, the speed of         presentation of the prompts is increased until the processor         detects an increase in user mistakes above a preset threshold;         and,     -   (d) pre-ring messaging so that an identifying name of a caller         is audibly announced to the user (for example: “it's mom”).

What follows is a detailed description of implementation of one embodiment of the interface of the present invention in the operation of a telecommunication device embedded in a plush toy. The plush toy is referred to herein as a “companion telecommunicator” such as it would be perceived by a child if the companion telecommunicator was a favorite plush doll. The programmed menu structure and logic flow that a user follows during operation of the companion telecommunicator are set out below. Appendix A hereto provides further detail, short of the actual code, of the sequence scripts for each step in the menu structure. Detailed actual coding is not provided as one skilled in the art would know how to program and implement the interface of the present invention given the level of detail disclosed.

To the user, such as a child, the companion telecommunicator appears to talk naturally, prompting the user with options. By simply squeezing the companion telecommunicator, the user places a call, makes emergency contact, records reminders and saves phone numbers. Call lists maintained by the companion telecommunicator processor are updated and sorted automatically, chronologically or according to popularity, with most recent or most frequently called numbers at the beginning. The companion telecommunicator tells the user that someone is calling by announcing the caller's name, or with a customized greeting, or with a standard telephone ring, a melody or by vibrating.

As seen in FIG. 4, companion telecommunicator 100 attaches to the clothes of a user 102 or for example to a user's backpack (not shown) for transport by the resilient clamping together of the hands 106. The companion telecommunicator may also have loops (not shown) that will attach to key rings or clips for easy transport.

After long periods of inactivity, companion telecommunicator 100 will go dormant. Companion telecommunicator 100 is woken up by squeezing its tummy 104 as seen in FIG. 5 gently for three seconds. Companion telecommunicator 100 greets user 102 then audibly broadcasts that it is in stand-by, speaking or whisper mode. Companion telecommunicator 100 may be intentionally made dormant or “put to sleep” by gently squeezing tummy 104 for three seconds. Companion telecommunicator 100 counts down “three”, “two”, “one” then says “good-bye”. Squeezing for three seconds will not however put the companion telecommunicator to sleep during a conversation or while announcing a call.

When companion telecommunicator 100 is in stand-by mode, it is ready to receive calls. User 102 can ensure that companion telecommunicator 100 is awake by giving it a gentle shake. If it giggles, it's awake. The companion telecommunicator's hands 106 are positioned as if clapping to put it in stand-by mode, as seen in FIG. 6. Thus companion telecommunicator 100 can hold on to user 102 while in stand-by mode as seen in FIG. 4.

Whisper mode is for private conversations. In whisper mode, the audible volume is lowered so that user 102 may hold the microphone 108 a embedded in, for example, the mouth 108 of companion telecommunicator 100 near to the user's ear. Companion telecommunicator 100 is put into whisper mode by lifting arms 110 out of plane A so that it looks like companion telecommunicator 100 is whispering as seen in FIGS. 5 and 7. Mouth 108 of companion telecommunicator 100 is brought to the user's ear so that the user can listen for directions. Speaking Mode allows the companion telecommunicator to speak loudly so that the audible directions can be heard by a group of people. Companion telecommunicator 100 is placed into speaking mode by opening the arms 110 as seen in FIG. 8. In speaking mode the arms have been rotated in plane A from the clapping position to the spread apart position.

To use companion telecommunicator 100, all user 102 has to do is hold the companion telecommunicator, listen and squeeze tummy 104. this depresses an internal push-button switch 112 mounted in rigid processor housing 114 seen in FIGS. 9-14. When the companion telecommunicator speaks via microphone 108 a, the user squeezes tummy 104 so as to depress switch 112 to tell the companion telecommunicator what the user wants. When the companion telecommunicator is in whisper or speaking mode, it talks to the user. To make a selection, the user squeezes the companion telecommunicator while it's talking, or during the moment before the next selection.

The companion telecommunicator uses a 3.6 volt lithium ion battery (not shown). If the battery is getting low the companion telecommunicator will periodically say “low battery”. This alarm will increase in frequency as the battery power gets lower.

Companion telecommunicator 100 uses a mechanical endoskeleton mounted within the arms and body of the telecommunicator so as to transmit the arm position information to the processor (not shown) housed within processor housing 114. A shoulder or shelf 116 is mounted onto or otherwise formed on the upper end of housing 114. As better seen in FIG. 13, shoulder 116 has an upper planar surface 116 a on which are pivotally mounted a pair of arm struts 118. Planar surface 116 a is parallel to plane A in which arm struts 118 rotate on stub shafts 120. Rotation of stub shafts 120 about axes of rotation B transmits the arm position information via a position sensor (not shown) to the processor within housing 114. Leaf spring 122 rigidly mounted between stub shafts 120 resiliently biases arm struts 118 into either the closed position of FIGS. 9 and 12 wherein hand paddles 124 mounted on the distal ends of arm struts 118 are resiliently clamped together or the speaking mode open position of FIG. 10 wherein arm struts 118 are rotated in direction C into their fully spread apart position.

As better seen in FIGS. 14 a-14 c and FIG. 15, arm struts 118 are themselves pivotally mounted to stub shafts 120 for rotation relative to stub shafts 120 about axes of rotation D on stub axles 126. Rotating arm struts 118 about axes D allows movement of the arms out of plane A so as to put the arms into the whisper mode position of FIG. 11.

Rotation of arm struts 118 about axes D rotates bevel gears 118 a on arm struts 118 in meshing engagement with crown gear 120 a on stub shafts 120. Thus, irrespective of the rotational position of stub shafts 120, elevating and lowering arm struts 118 rotates crown gears 120 a thereby signaling to the processor the vertical position information of arm struts 118. Stub shaft 120 is mounted by means of pin 126 shown exploded radially outwardly in FIG. 15. Thus contrasting FIGS. 14 b and 14 c, although between the two figures the rotational position of stub shaft 120 has not changed, the arm strut 118 has been elevated in FIG. 14 c thereby rotating crown gear 120 a relative to stub shaft 120.

An alternative embodiment is illustrated in FIG. 16 in which, as labeled, all of the various components are built into the processor housing with the exception of a remote speaker and microphone for which only the respective connectors are illustrated.

The housing 114 is enlarged so as to enclose shoulder 116, the gear ends of arm struts 118, the gears, etc. Consistent with all embodiments of housing 114, the circuit boards 130 containing the processors, the power supply, and the audio amplifier are all contained within the egg-shaped housing, tilted for example as illustrated so as to optimize use of the interior space of the housing. Arm struts rotate relative to the housing in cut-out channels 128.

The audible menu for the companion telecommunicator works like a menu tree. Every choice made by the user leads to more choices until the function that the user wants is presented. Some prompts appear in more than one menu.

When the companion telecommunicator asks “what would you like to do?” the user has several choices. Each choice performs a specific function or presents more options. The choices are presented in the following order: “Present Lists”, “Enter A Number”, “Play Sound Clips”, “Record Sound Clip”, “Provide Status Information”, and “Set Preferences”. The choices are audibly repeated by the companion telecommunicator sequentially several times. If the user does not make a choice, the companion telecommunicator returns to stand-by mode.

The “Present Lists” choice lists stored phone numbers to call. The stored telephone numbers are sorted for presentation depending on the type of list selected. The choices are “Personal Call List”, “Emergency Call List”, “Incoming History List” and “Outgoing History List”. The Personal Call List is automatically updated, according to frequency of use. The Emergency Call List presents the most important numbers first. The Incoming History List is updated according to the last number that called the companion telecommunicator. The Outgoing History List sorts the user's calls, starting with the most recent number.

The “Enter a Number” choice guides the user through telephone number entry and lets the user add the number to the phone list.

The “Sound Clip” choice lets the user record, play back or delete sound clips. Sound clips may be recorded during conversations, as reminders or transferred from the network or the user's home computer.

The “Provide Status Information” choice announces the user's phone number and the time and date, then tells the user if there are messages waiting, and reports battery level, signal strength, roaming status, available memory, and the like.

The “Set Preferences” choice customizes the way the companion telecommunicator responds and presents information.

The user can cancel any choice and return to the previous menu at any time by squeezing the companion telecommunicator three times.

Any time the user needs assistance on a particular menu item, the user squeezes the companion telecommunicator's hand 106 when the user is in that part of the menu. A sensor in the hand triggers the processor provide context sensitive audible help prompts.

To answer a call in Whisper Mode, the user lifts the companion telecommunicator's hands 106 to mouth 108, then places companion telecommunicator 100 near the user's ear. To answer a call in Speaking Mode, user 102 opens the companion telecommunicator's arms 110. The volume is automatically increased so as to be loud enough for a group of people to hear the conversation.

To terminate a call, user 102 places the companion telecommunicator in stand-by mode by closing arms 110.

For the user to place a call using Enter A Number menu:

-   -   1. The user places the companion telecommunicator in Whisper or         Speaking Mode.     -   2. When the companion telecommunicator says “enter number”, the         user squeezes once.     -   3. The companion telecommunicator will count from zero to nine         and say “place call”.     -   4. The user squeezes the companion telecommunicator when the         user hears the right digit.     -   5. The user repeats Step 4 for each digit in the number the user         wishes to call.     -   6. If the user makes a mistake, the user squeezes the companion         telecommunicator twice. When the companion telecommunicator says         “erase last digit entered”, the user squeezes once.     -   7. To review the digits entered, the user squeezes the companion         telecommunicator twice. When the companion telecommunicator says         “review digits entered”, the user squeezes once.     -   8.

The user squeezes when the user hears: “Set Preferences”. The companion telecommunicator will report the current prompt level. The user squeezes once to choose the other level.

The Getting Status Information option allows the user to get status information about the companion telecommunicator. The user places the companion telecommunicator in Whisper or Speaking Mode. The user squeezes when the user hears: “Provide Status Information”. The companion telecommunicator announces the telephone number and time and date and tells the user if the user has messages waiting, then reports current battery level, signal strength, roaming status, memory available in minutes and seconds, the current billing rate, and balance remaining on card (optional). The user squeezes to advance to the next report.
